Method and device for transmitting content

a content and transmission method technology, applied in the field of telecommunications, can solve the problems of unpopular file downloading time, method failure to find for obtaining a file of the same order, and existing methods of sharing accordingly deliver very long downloading time for unpopular files, so as to increase or decrease the response time, increase the response time, the effect of increasing or decreasing the distortion between the response time of files

Benefits of technology

[0029]This value A can actually be used to increase or decrease the distortion between the response time of files having different levels of popularity. As a function of the value of the parameter A, the response times for less popular files can be made as close as preferred to the response times for very popular files. On the contrary, it is possible to increase the response time for the less popular files even more to reduce those times for very popular files. Finally, it is possible to reverse the tendency and to make the response time of less popular files shorter than response time of very popular files.
[0030]It therefore becomes possible to attain approximately equal performances in terms of transmission times of same-sized files, irrespective of the number of suppliers, that is, the number of available copies of the content wanted by the requester.
[0032]It is noted that executing an embodiment of the present invention needs no complex calculating and therefore no consumption of resources on the part of the suppliers of the content.
[0049]This avoids any risk of congestion of the network due to fictitious requests sent by suppliers to find out the estimation Ni of the number of suppliers of the content.
[0058]It is noted that the application implementing the process forming the subject matter of an embodiment of the present invention can be parametered so as to increase or decrease distortion between the response time of files of different levels of popularity. As a function of the value of the parameter A, the response time for the less popular files can be made as close as wanted to the response time for very popular files. On the contrary, it is possible to increase further still the response times for less popular files to then reduce those for very popular files. Finally, it is possible to reverse the tendency and make the response times of less popular files shorter than the response times of very popular files.

Problems solved by technology

In particular, a less popular file will take longer to download as there are fewer users owning a copy, from which the file can be requested.
However, users of eMule can see that this method fails to find for obtaining a file of the same order for popular and unpopular files.
Existing methods of sharing accordingly deliver very long downloading time for unpopular files, that is, those for which there are few copies.

Embodiment Construction

[0081]Throughout the description, user or peer refers to a terminal with means of running a content-sharing application, especially for downloading content over a network. For example, these are personal computers fitted with a modem or an Internet connection box and adequate programs, some of which are cited hereinabove.

[0082]FIG. 1 shows five users or peers115 to 130 connected to a communications network 105 and using file-sharing applications. The communications network 105 is, for example, the Internet. At least one user is running a computer program (not shown) loadable into a computer system, said program containing instructions for executing the process forming the subject of an embodiment of the present invention, such as described hereinbelow. This program is stored on a data-storage medium (not shown) readable by a computer or a microprocessor, removable or not, containing instructions of this program, for example, a hard drive, a flash drive or a compact disc.

Abstract

A process and device are provided for transmitting content i by a supplier of this content. The process includes: a step of receiving by the supplier a transmission request of the content i originating from a requester, a step of obtaining by the supplier an estimation Ni of a number of suppliers of the content, and a step of transmitting the content i, during which the supplier sends the requester at least part of the content i by allocating to the requester an average proportion of the bandwidth allocated by this supplier to distribution of content calculated in the form of a coefficient, which is function of the number Ni of suppliers of the content i and of a real value A, common to all the content to be transmitted, serving to adjust the impact on the coefficient of the number Ni of suppliers of the content i.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application is a Section 371 National Stage Application of International Application No. PCT / FR2010 / 052816, filed Dec. 20, 2010, which is incorporated by reference in its entirety and published as WO 2011 / 080465 on Jul. 7, 2011, not in English.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]None.THE NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT[0003]None.FIELD OF THE DISCLOSURE[0004]The present disclosure relates to a process and a device for content transmission. It particularly relates to the field of telecommunications, and more particularly telecommunications over a network, for example the Internet, and that of Internet computer applications such as content distribution (Content Distribution) and peer-to-peer applications or P2P (peer-to-peer in English).BACKGROUND OF THE DISCLOSURE[0005]Peer-to-peer file-sharing applications are widely used on the Internet and represent an important part of traffic exchang...
